Johne's disease

This is an infectious disease in cattle designated by law due to Mycobacterium paratuberculosis that is characterized by persistent diarrhea and progressive emaciation. Its prognosis is poor. Since this disease occurs after a latent period for a few years - over ten years, purification is very difficult once it occurs. Straw sandal-like thickening of the intestinal wall (photo) is a characteristic finding. There are some specimens in this museum including the first case in Japan.
